Research Engineer

Oxford Dynamics is hiring a Research Engineer to bridge frontier machine-learning research and product development. The role applies research in reinforcement learning, RLHF, multi-objective policy optimisation and LLM post-training to capabilities deployed in defence and security systems.

Responsibilities:

• Apply and adapt machine-learning and reinforcement-learning research to OD's product roadmap, translating research direction into shippable capability
• Design, train and evaluate models using reinforcement learning, RLHF and multi-objective policy optimization, balancing competing objectives such as accuracy, safety, latency and cost
• Work on LLM post-training: fine-tuning, alignment, reward modelling and rigorous evaluation
• Prototype fast, then work with the engineering teams to harden what works into production
• Define how frontier models can be evaluated and how decision making can be audited
• Engage directly with customers and stakeholders, explaining technical approaches to non-specialists and feeding real-world needs back into the research agenda
• Help shape OD's research and product vision, bringing a clear point of view on where the field is heading and what OD should build next
